The election year was tumultuous; it was marked by the assassination of Civil Rights Movement leader Martin Luther King Jr., subsequent King assassination riots across the nation, the assassination of Kennedy, and widespread opposition to the Vietnam War across university campuses. Nixon ran on a campaign that promised to restore law and order to the nation's cities and provide new leadership in the Vietnam War. A year later, he would popularize the term "silent majority" to describe those he viewed as being his target voters. He also pursued a "Southern strategy" designed to win conservative Southern white voters who had traditionally supported the Democratic Party. Humphrey promised to continue Johnson's War on Poverty and to support the Civil Rights Movement. Humphrey trailed badly in polls taken in late August but narrowed Nixon's lead after Wallace's candidacy collapsed and Johnson suspended bombing in the Vietnam War.

Nixon won a plurality of the popular vote by a narrow margin, but won by a large margin in the Electoral College, carrying most states outside of the Northeast. Wallace won five states in the Deep South and ran well in some ethnic enclave industrial districts in the North; he is the most recent third party candidate to win a state. This was the first presidential election after the passage of the Voting Rights Act of 1965, which had led to mass enfranchisement of racial minorities throughout the country, especially in the South. Nixon's victory marked the start of a period of Republican dominance in presidential elections, as Republicans won five of the next six elections.

In the election of 1964, incumbent Democrat Lyndon B. Johnson won the largest popular vote landslide in U.S. Presidential election history over Republican Barry Goldwater. During the presidential term that followed, Johnson was able to achieve many political successes, including the passage of the Great Society domestic programs (including "War on Poverty" legislation), landmark civil rights legislation, and the continued exploration of space. Despite making significant achievements, his popular support would be short-lived. At the same time, the country endured large-scale race riots in the streets of its larger cities, along with a generational revolt of young people and violent debates over foreign policy. The emergence of the hippiecounterculture, the rise of New Left activism, and the emergence of the Black Power movement exacerbated social and cultural clashes between classes, generations, and races. Adding to the national crisis, on April 4, 1968, civil rights leader Rev. Martin Luther King, Jr., was assassinated, igniting further mass rioting and chaos, including Washington, D.C., where there was rioting within just a few blocks of the White House and machine guns were stationed on the Capitol steps to protect it.[2]

The most important reason for the precipitous decline of President Johnson's popularity was the Vietnam War, which he greatly escalated during his time in office. By late 1967, over 500,000 American soldiers were fighting in Vietnam. Draftees made up 42 percent of the military in Vietnam, but suffered 58% of the casualties as nearly 1000 Americans a month were killed and many more were injured.[3] Johnson's position was particularly damaged when the national news media began to focus on the high costs and ambiguous results of escalation, despite his repeated efforts to downplay the seriousness of the situation.

In early January 1968, Secretary of Defense Robert McNamara stated that the war would be winding down as the North Vietnamese were losing their will to fight, but shortly thereafter, they launched the Tet Offensive, in which the North Vietnamese and Communist Vietcong forces launched simultaneous attacks on all government strongholds in South Vietnam. Though a U.S. military victory, Tet led many Americans to ponder whether the war was winnable or worth it. In addition, voters felt they could not trust their government's assessment and reporting of the war effort. The Pentagon called for sending several hundred thousand more soldiers to Vietnam. Johnson's approval ratings fell below 35%, and the Secret Service refused to let the president make public appearances on the campuses of American colleges and universities, due to his extreme unpopularity among college students. The Secret Service also prevented Johnson from appearing at the 1968 Democratic National Convention in Chicago, because it could not guarantee his safety from assassination.[4]

The front-runner for the Republican nomination was former Vice President Richard Nixon, who formally began campaigning in January 1968.[5] Nixon had worked tirelessly behind the scenes and was instrumental in Republican gains in Congress and governorships in the 1966 midterm elections. Thus, the party machinery and many of the new congressmen and governors supported him. Still, there was wariness in the Republican ranks over Nixon, who had lost the 1960 election and then lost the 1962 California gubernatorial election. Some hoped a more "electable" candidate would emerge. To a great extent the story of the 1968 Republican primary campaign and nomination is the story of one Nixon opponent after another entering the race and then dropping out. Nixon was always clearly the front runner throughout the contest because of his superior organization, and he easily defeated the rest of the field.

Nixon's first challenger was Michigan Governor George W. Romney. A Gallup poll in mid-1967 showed Nixon with 39%, followed by Romney with 25%. However, Romney, after a fact finding trip to Vietnam, told Detroit talk show host Lou Gordon (journalist) that he had been "brainwashed" by the military and the diplomatic corps into supporting the Vietnam War; the remark led to weeks of ridicule in the national news media. Since he had turned against American involvement in Vietnam, Romney planned to run as the anti-war Republican version of Eugene McCarthy.[6] However, following his "brainwashing" comment, Romney's support faded steadily, and with polls showing him far behind Nixon he withdrew from the race on February 28, 1968.[7]

Senator Charles Percy was considered another potential threat to Nixon even before Romney's withdrawal, and had planned on potentially waging an active campaign after securing a role as Illinois's favorite son. Later however Percy declined to have his name presented on the ballot for the Illinois presidential primary, and while he never disclaimed his interest in the presidential nomination, he no longer actively sought it either.[8]

Nixon won a resounding victory in the important New Hampshire primary on March 12, with 78% of the vote. Anti-war Republicans wrote in the name of New York Governor Nelson Rockefeller, the leader of the Republican Party's liberal wing, who received 11% of the vote and became Nixon's new challenger. Rockefeller had originally not intended to run, having discounted a campaign for the nomination in 1965 and planned on making Senator Jacob Javits the favorite son, either in preparation of a presidential campaign or to secure him the second spot on the ticket; as Rockefeller warmed to the idea of entering the race again however, Javits moved his attentions back towards seeking a third term in the Senate.[9] Nixon led Rockefeller in the polls throughout the primary campaign, and though Rockefeller defeated Nixon and Governor John Volpe in the Massachusetts primary on April 30, he otherwise fared poorly in state primaries and conventions, having declared too late to place his name on state ballots.

By early spring, California GovernorRonald Reagan, the leader of the Republican Party's conservative wing, had become Nixon's chief rival. In the Nebraska primary on May 14, Nixon won with 70% of the vote to 21% for Reagan and 5% for Rockefeller. While this was a wide margin for Nixon, Reagan remained Nixon's leading challenger. Nixon won the next primary of importance, Oregon, on May 15 with 65% of the vote, and won all the following primaries except for California (June 4), where only Reagan appeared on the ballot. Reagan's victory in California gave him a plurality of the nationwide primary vote, but his poor showing in most other state primaries left him far behind Nixon in the actual delegate count.

The following candidates were frequently interviewed by major broadcast networks, were listed in publicly published national polls, or ran a campaign that extended beyond their home delegation in the case of favorite sons.

Humphrey received 166,463 votes in the primaries.

Because Lyndon Johnson had been elected to the presidency only once, in 1964, and had served less than two full years of the term before that, the 22nd Amendment did not disqualify him from running for another term.[15][16] As a result, it was widely assumed when 1968 began that President Johnson would run for another term, and that he would have little trouble winning the Democratic nomination.

Despite growing opposition to Johnson's policies in Vietnam, it appeared that no prominent Democratic candidate would run against a sitting president of his own party. It was also accepted at the beginning of the year that Johnson's record of domestic accomplishments would overshadow public opposition to the Vietnam War and that he would easily boost his public image after he started campaigning.[17] Even Senator Robert F. Kennedy from New York, an outspoken critic of Johnson's policies with a large base of support, initially declined to run against Johnson in the primaries. Poll numbers also suggested that a large share of Americans who opposed the Vietnam War felt the growth of the anti-war hippie movement among younger Americans was not helping their cause.[17] On January 30, however, claims by the Johnson administration that a recent troop surge would soon bring an end to the war were severely discredited when the Tet Offensive broke out. Although the American military was eventually able to fend off the attacks, and also inflict heavy losses among the communist opposition, the ability of the North Vietnamese Army and Viet Cong to launch large scale attacks during the Tet Offensive's long duration greatly weakened American support for the military draft and further combat operations in Vietnam.[18]

In time, only Senator Eugene McCarthy from Minnesota proved willing to challenge Johnson openly. Running as an anti-war candidate in the New Hampshire primary, McCarthy hoped to pressure the Democrats into publicly opposing the Vietnam War. Since New Hampshire was the first presidential primary of 1968, McCarthy poured most of his limited resources into the state. He was boosted by thousands of young college students led by youth coordinator Sam Brown,[19] who shaved their beards and cut their hair to be "Clean for Gene". These students organized get-out-the-vote drives, rang doorbells, distributed McCarthy buttons and leaflets, and worked hard in New Hampshire for McCarthy. On March 12, McCarthy won 42 percent of the primary vote to Johnson's 49 percent, a shockingly strong showing against an incumbent president. Even more impressively, since Johnson had more than 24 supporters running for the Democratic National Convention delegate slots to be filled in the election, while McCarthy's campaign organized more strategically, McCarthy won 20 of the 24 delegates. This gave McCarthy's campaign legitimacy and momentum.

Sensing Johnson's vulnerability, Senator Robert F. Kennedy announced his candidacy four days after the New Hampshire primary. Thereafter, McCarthy and Kennedy engaged in a series of state primaries. Kennedy won most of the primaries in which he and McCarthy were in direct competition.

On March 31, 1968, following the New Hampshire primary and Kennedy's entry into the election, the president announced to the nation in a televised speech that he was suspending all bombing of North Vietnam in favor of peace talks. Johnson concluded his speech and startled the nation by announcing "With America's sons in the fields far away, with America's future under challenge right here at home, with our hopes and the world's hopes for peace in the balance every day, I do not believe that I should devote an hour or a day of my time to any personal partisan causes or to any duties other than the awesome duties of this office—the presidency of your country. Accordingly, I shall not seek, and I will not accept, the nomination of my party for another term as your President." Not discussed publicly at the time was Johnson's concern he might not survive another term—Johnson's health was poor, and he had suffered a serious heart attack in 1955 while serving in the U.S. Senate. Indeed, he died on January 22, 1973, only two days after the new presidential term concluded. Bleak political forecasts also contributed to Johnson's withdrawal; internal polling by Johnson's campaign in Wisconsin, the next state to hold a primary election, showed the President trailing badly.

Historians have debated just why Johnson quit a few days after his weak showing in New Hampshire. Jeff Shesol says Johnson wanted out of the White House but also wanted vindication; when the indicators turned negative he decided to leave.[20] Lewis L. Gould maintains that Johnson had neglected the party, was hurting it by his Vietnam policies, and underestimated McCarthy's strength until the very last minute, when it was too late for Johnson to recover.[21] Randall Bennett Woods said Johnson realized he needed to leave in order for the nation to heal.[22]Robert Dallek writes that Johnson had no further domestic goals, and realized that his personality had eroded his popularity. His health was not good, and he was preoccupied with the Kennedy campaign; his wife was pressing for his retirement and his base of support continued to shrink. Leaving the race would allow him to pose as a peacemaker.[23] Anthony J. Bennett, however, claims Johnson "had been forced out of a re-election race in 1968 by outrage over his policy in Southeast Asia".[24]

It has also been reported that Johnson decided to wind down his re-election bid after popular and influential CBS News anchor Walter Cronkite turned against the president's policy in Vietnam and recommended peace negotiations during a CBS News editorial which aired on February 27.[25][26] After later watching Cronkite's editorial, Johnson allegedly exclaimed "if I've lost Cronkite, I've lost Middle America."[25] Issues surrounding reports of this allegation have raised questions about its accuracy,[27] such as the fact that Johnson was attending Texas Governor John Connally's birthday gala in Austin, Texas, when Cronkite's editorial aired and thus was unable to see the original broadcast.[27] However, Cronkite and CBS News correspondent Bob Schieffer defended reports that the remark had been made and claimed that members of Johnson's inner circle who had watched the editorial with the president, including presidential aide George Christian and journalist Bill Moyers, were able to confirm its accuracy to them at a later time.[28][29] Schieffer, who was serving as a reporter for the Star-Telegram's WBAP television station in Fort Worth, Texas, when Cronkite's editorial aired, acknowledged reports that the president saw the editorial's original broadcast were inaccurate,[29] but claimed the president was able to watch a taping of it the morning after it aired and then made the remark.[29]

With Johnson's withdrawal, the Democratic Party quickly split into four factions.

The first faction consisted of labor unions and big-city party bosses (led by Mayor Richard J. Daley). This group had traditionally controlled the Democratic Party since the days of President Franklin D. Roosevelt, and they feared loss of their control over the party. After Johnson's withdrawal this group rallied to support Hubert Humphrey, Johnson's vice-president; it was also believed that President Johnson himself was covertly supporting Humphrey, despite his public claims of neutrality.

The second faction, which rallied behind Senator Eugene McCarthy, was composed of college students, intellectuals, and upper-middle-class whites who had been the early activists against the war in Vietnam; they perceived themselves as the future of the Democratic Party.

The third group was primarily composed of Catholics, blacks and other minorities as well as several antiwar groups; these groups rallied behind Senator Robert F. Kennedy.

The fourth group consisted of white Southern Democrats. Some older men, remembering the New Deal's positive impact upon the rural South, supported Vice-President Humphrey. Many would rally behind the third-party campaign of former Alabama Governor George C. Wallace as a "law and order" candidate.

Since the Vietnam War had become the major issue that was dividing the Democratic Party, and Johnson had come to symbolize the war for many liberal Democrats, Johnson believed that he could not win the nomination without a major struggle, and that he would probably lose the election in November to the Republicans. However, by withdrawing from the race he could avoid the stigma of defeat, and he could keep control of the party machinery by giving the nomination to Humphrey, who had been a loyal vice-president.[30] Milne (2011) argues that, in terms of foreign-policy in the Vietnam War, Johnson at the end wanted Nixon to be president rather than Humphrey, since Johnson agreed with Nixon, rather than Humphrey, on the need to defend South Vietnam from communism.[31] However, Johnson's telephone calls show that Johnson believed the Nixon camp was deliberately sabotaging the Paris peace talks. He told Humphrey, who refused to use allegations based on illegal wiretaps of a presidential candidate. Nixon himself called Johnson and denied the allegations. Dallek concludes that Nixon's advice to Saigon made no difference, and that Humphrey was so closely identified with Johnson's unpopular policies that no last-minute deal with Hanoi could have affected the election.[32]

After Johnson's withdrawal, Vice President Hubert Humphrey announced his candidacy. Kennedy was successful in four state primaries (Indiana, Nebraska, South Dakota, and California) and McCarthy won six (Wisconsin, Pennsylvania, Massachusetts, Oregon, New Jersey, and Illinois). However, in primaries where they campaigned directly against one another, Kennedy won three primaries (Indiana, Nebraska, and California) and McCarthy won one (Oregon).[33] Humphrey did not compete in the primaries, leaving that job to favorite sons who were his surrogates, notably Senator George A. Smathers from Florida, Senator Stephen M. Young from Ohio, and Governor Roger D. Branigin of Indiana. Instead, Humphrey concentrated on winning the delegates in non-primary states, where party leaders such as Chicago Mayor Richard J. Daley controlled the delegate votes in their states. Kennedy defeated Branigin and McCarthy in the Indiana primary, and then defeated McCarthy in the Nebraska primary. However, McCarthy upset Kennedy in the Oregon primary.

After Kennedy's defeat in Oregon, the California primary was seen as crucial to both Kennedy and McCarthy. McCarthy stumped the state's many colleges and universities, where he was treated as a hero for being the first presidential candidate to oppose the war. Kennedy campaigned in the ghettos and barrios of the state's larger cities, where he was mobbed by enthusiastic supporters. Kennedy and McCarthy engaged in a television debate a few days before the primary; it was generally considered a draw. On June 4, Kennedy narrowly defeated McCarthy in California, 46%–42%. However, McCarthy refused to withdraw from the race and made it clear that he would contest Kennedy in the upcoming New York primary, where McCarthy had much support from anti-war activists in New York City. The New York primary quickly became a moot point, however, for Kennedy was shot shortly after midnight on June 5; he died twenty-six hours later. Kennedy had just given his victory speech in a crowded ballroom of the Ambassador Hotel in Los Angeles; he and his aides then entered a narrow kitchen pantry on their way to a banquet room to meet with reporters. In the pantry Kennedy and five others were shot by Sirhan Sirhan, a 24-year-old RosicrucianPalestinian of Christian background and Jordanian citizenship, who hated Kennedy because of his support for Israel. Sirhan admitted his guilt, was convicted of murder, and is still in prison.[34] In recent years some have cast doubt on Sirhan's guilt, including Sirhan himself, who said he was "brainwashed" into killing Kennedy and was a patsy.[35]

Political historians still debate whether Kennedy could have won the Democratic nomination had he lived. Some historians, such as Theodore H. White and Arthur M. Schlesinger, Jr., have argued that Kennedy's broad appeal and famed charisma would have convinced the party bosses at the Democratic Convention to give him the nomination. Jack Newfield, author of RFK: A Memoir, stated in a 1998 interview that on the night he was assassinated, "[Kennedy] had a phone conversation with Mayor Daley of Chicago, and Mayor Daley all but promised to throw the Illinois delegates to Bobby at the convention in August 1968. I think he said to me, and Pete Hamill, 'Daley is the ball game, and I think we have Daley.'"[36] However, other writers such as Tom Wicker, who covered the Kennedy campaign for The New York Times, believe that Humphrey's large lead in delegate votes from non-primary states, combined with Senator McCarthy's refusal to quit the race, would have prevented Kennedy from ever winning a majority at the Democratic Convention, and that Humphrey would have been the Democratic nominee even if Kennedy had lived. The journalist Richard Reeves and historian Michael Beschloss have both written that Humphrey was the likely nominee, and future Democratic National Committee chairman Larry O'Brien wrote in his memoirs that Kennedy's chances of winning the nomination had been slim, even after his win in California.

Robert Kennedy's death altered the dynamics of the race. Although Humphrey appeared the prohibitive favorite for the nomination, thanks to his support from the traditional power blocs of the party, he was an unpopular choice with many of the anti-war elements within the party, who identified him with Johnson's controversial position on the Vietnam War. However, Kennedy's delegates failed to unite behind a single candidate who could have prevented Humphrey from getting the nomination. Some of Kennedy's support went to McCarthy, but many of Kennedy's delegates, remembering their bitter primary battles with McCarthy, refused to vote for him. Instead, these delegates rallied around the late-starting candidacy of Senator George McGovern of South Dakota, a Kennedy supporter in the spring primaries who had presidential ambitions himself. This division of the anti-war votes at the Democratic Convention made it easier for Humphrey to gather the delegates he needed to win the nomination.

When the 1968 Democratic National Convention opened in Chicago, thousands of young activists from around the nation gathered in the city to protest the Vietnam War. On the evening of August 28, in a clash which was covered on live television, Americans were shocked to see Chicago police brutally beating anti-war protesters in the streets of Chicago in front of the Conrad Hilton Hotel. While the protesters chanted "the whole world is watching", the police used clubs and tear gas to beat back or arrest the protesters, leaving many of them bloody and dazed. The tear gas wafted into numerous hotel suites; in one of them Vice President Humphrey was watching the proceedings on television. The police said that their actions were justified because numerous police officers were being injured by bottles, rocks, and broken glass that were being thrown at them by the protestors. The protestors had also yelled insults at the police, calling them "pigs" and other epithets. The anti-war and police riot divided the Democratic Party's base: some supported the protestors and felt that the police were being heavy-handed, but others disapproved of the violence and supported the police. Meanwhile, the convention itself was marred by the strong-arm tactics of Chicago's mayor Richard J. Daley (who was seen on television angrily cursing Senator Abraham Ribicoff from Connecticut, who made a speech at the convention denouncing the excesses of the Chicago police). In the end, the nomination itself was anti-climactic, with Vice-President Humphrey handily beating McCarthy and McGovern on the first ballot.

After the delegates nominated Humphrey, the convention then turned to selecting a vice-presidential nominee. The main candidates for this position were Senators Edward M. Kennedy from Massachusetts, Edmund Muskie from Maine, and Fred R. Harris from Oklahoma; Governors Richard Hughes of New Jersey and Terry Sanford of North Carolina; Mayor Joseph Alioto of San Francisco, California; former Deputy Secretary of Defense Cyrus Vance; and Ambassador Sargent Shriver from Maryland. Another idea floated was to tap Republican Governor Nelson Rockefeller of New York, one of the most liberal Republicans. Ted Kennedy was Humphrey's first choice, but the senator turned him down. After narrowing it down to Senator Muskie and Senator Harris, Vice-President Humphrey chose Muskie, a moderate and environmentalist from Maine, for the nomination. The convention complied with the request and nominated Senator Muskie as Humphrey's running mate.

The publicity from the anti-war riots crippled Humphrey's campaign from the start, and it never fully recovered.[38] Before 1968 the city of Chicago had been a frequent host for the political conventions of both parties; since 1968 only one national convention has been held there (the Democratic convention of 1996, which nominated Bill Clinton for a second term). Many believe that this is due in part to the violence and chaos of the 1968 convention.

The American Independent Party, which was established in 1967 by Bill and Eileen Shearer, nominated former Alabama Governor George Wallace – whose pro-segregation policies had been rejected by the mainstream of the Democratic Party – as the party's candidate for president. The impact of the Wallace campaign was substantial, winning the electoral votes of several states in the Deep South. He appeared on the ballot in all fifty states, but not the District of Columbia. Although he did not come close to winning any states outside the South, Wallace was the most popular 1968 presidential candidate among young men.[46] Wallace also proved to be popular among blue-collar workers in the North and Midwest, and he took many votes which might have gone to Humphrey.[citation needed]

Wallace did not expect to win the election – his strategy was to prevent either major party candidate from winning a preliminary majority in the Electoral College. He had his electors pledge to vote not necessarily for him but rather for whomever he directed them to support – his objective was not to move the election into the U.S. House of Representatives, but rather to give himself the bargaining power to determine the winner. Wallace's running mate was retired U.S. Air Force General Curtis LeMay.

Prior to deciding on LeMay, Wallace gave serious consideration to former U.S. Senator, Governor, and Baseball Commissioner A.B. Happy Chandler of Kentucky as his running mate.[47] Chandler and Wallace met a number of times, however, Chandler said that he and Wallace were unable to come to an agreement regarding their positions on racial matters. Paradoxically, Chandler supported the segregationist Dixiecrats in the 1948 presidential elections. But, after being reelected Governor of Kentucky in 1955, he used National Guard troops to enforce school integration.[48]

LeMay embarrassed Wallace's campaign in the fall by suggesting that nuclear weapons could be used in Vietnam.

Nixon developed a "Southern strategy" that was designed to appeal to conservative white southerners, who traditionally voted Democratic, but were opposed to Johnson and Humphrey's support for the civil rights movement, as well as the rioting that had broken out in the ghettos of most large cities. Wallace, however, won over many of the voters Nixon targeted, effectively splitting the conservative vote. Indeed, Wallace deliberately targeted many states he had little chance of carrying himself in the hope that by splitting the conservative vote with Nixon he would give those states to Humphrey and, by extension, boost his own chances of denying both opponents an Electoral College majority.[50]

Since he was well behind Nixon in the polls as the campaign began, Humphrey opted for a slashing, fighting campaign style. He repeatedly – and unsuccessfully – challenged Nixon to a televised debate, and he often compared his campaign to the successful underdog effort of President Harry Truman, another Democrat who had trailed in the polls, in the 1948 presidential election. Humphrey predicted that he, like Truman, would surprise the experts and win an upset victory.[citation needed]

Nixon campaigned on a theme to restore "law and order,"[51] which appealed to many voters angry with the hundreds of violent riots that had taken place across the country in the previous few years. Following the murder of Martin Luther King in April 1968, there was severe rioting in Detroit and Washington, D.C., and President Johnson had to call out the U.S. Army to protect lives and property as smoke from burning buildings a few blocks away drifted across the White House lawn. However, Vice-President Humphrey criticized the "law and order" issue, claiming that it was a subtle appeal to white racial prejudice.[52] Nixon also opposed forced busing to desegregate schools.[53] Proclaiming himself a supporter of civil rights, he recommended education as the solution rather than militancy. During the campaign, Nixon proposed government tax incentives to African Americans for small businesses and home improvements in their existing neighborhoods.[54]

During the campaign, Nixon also used as a theme his opposition to the decisions of Chief Justice Earl Warren. Many conservatives were critical of Chief Justice Warren for using the Supreme Court to promote liberal policies in the fields of civil rights, civil liberties, and the separation of church and state. Nixon promised that if he were elected president, he would appoint justices who would take a less-active role in creating social policy.[55] In another campaign promise, he pledged to end the draft.[56] During the 1960s, Nixon had been impressed by a paper he had read by Professor Martin Anderson of Columbia University. Anderson had argued in the paper for an end to the draft and the creation of an all-volunteer army.[57] Nixon also saw ending the draft as an effective way to undermine the anti-Vietnam war movement, since he believed affluent college-age youths would stop protesting the war once their own possibility of having to fight in it was gone.[58]

Humphrey, meanwhile, promised to continue and expand the Great Society welfare programs started by President Johnson, and to continue the Johnson Administration's "War on Poverty." He also promised to continue the efforts of Presidents Kennedy and Johnson, and the Supreme Court, in promoting the expansion of civil rights and civil liberties for minority groups. However, Humphrey also felt constrained for most of his campaign in voicing any opposition to the Vietnam War policies of President Johnson, due to his fear that Johnson would reject any peace proposals he made and undermine his campaign. As a result, early in his campaign Humphrey often found himself the target of anti-war protestors, some of whom heckled and disrupted his campaign rallies.

After the Democratic Convention in late August, Humphrey trailed Nixon by double digits in most polls, and his chances seemed hopeless. According to Time magazine, "The old Democratic coalition was disintegrating, with untold numbers of blue-collar workers responding to Wallace's blandishments, Negroes threatening to sit out the election, liberals disaffected over the Vietnam War, the South lost. The war chest was almost empty, and the party's machinery, neglected by Lyndon Johnson, creaked in disrepair."[59] Calling for "the politics of joy," and using the still-powerful labor unions as his base, Humphrey fought back. In order to distance himself from Johnson and to take advantage of the Democratic plurality in voter registration, Humphrey stopped being identified in ads as "Vice-President Hubert Humphrey," instead being labelled "Democratic candidate Hubert Humphrey." Humphrey attacked Wallace as a racist bigot who appealed to the darker impulses of Americans. Wallace had been rising in the polls, and peaked at 21% in September, but his momentum stopped after he selected Curtis LeMay as his running mate. Curtis LeMay's suggestion of tactical nuclear weapons being used in Vietnam conjured up memories of the 1964 Goldwater campaign.[10] Labor unions also undertook a major effort to win back union members who were supporting Wallace, with substantial success. Polls that showed Wallace winning almost one-half of union members in the summer of 1968 showed a sharp decline in his union support as the campaign progressed. As election day approached and Wallace's support in the North and Midwest began to wane, Humphrey finally began to climb in the polls.

In October, Humphrey—who was rising sharply in the polls due to the collapse of the Wallace vote—began to distance himself publicly from the Johnson administration on the Vietnam War, calling for a bombing halt. The key turning point for Humphrey's campaign came when President Johnson officially announced a bombing halt, and even a possible peace deal, the weekend before the election. The "Halloween Peace" gave Humphrey's campaign a badly needed boost. In addition, Senator Eugene McCarthy finally endorsed Humphrey in late October after previously refusing to do so, and by election day the polls were reporting a dead heat.[60]

The Nixon campaign had anticipated a possible "October surprise," a peace agreement produced by the Paris negotiations, to boost Humphrey and thwarted any last-minute chances of a "Halloween Peace." Nixon told campaign aide and his future White House Chief of StaffH. R. Haldeman to put a "monkey wrench" into an early end to the war.[61] Johnson was enraged and said that Nixon had "blood on his hands" and that Senate Minority LeaderEverett Dirksen agreed with Johnson that such action was "treason."[62][63] Defense Secretary Clark Clifford considered the moves an illegal violation of the Logan Act.[64] A former director of the Nixon Library called it a "covert action" which "laid the skulduggery of his presidency."[61]

Bryce Harlow, former Eisenhower White House staff member, claimed to have "a double agent working in the White House....I kept Nixon informed." Harlow and Nixon's future National Security Advisor and Secretary of StateHenry Kissinger, who was friendly with both campaigns and guaranteed a job in either a Humphrey or Nixon administration, separately predicted Johnson's "bombing halt": "The word is out that we are making an effort to throw the election to Humphrey. Nixon has been told of it," Democratic senator George Smathers informed Johnson.[65]

Nixon asked Anna Chennault to be his "channel to Mr. Thieu" in order to advise him to refuse participation in the talks, in what is sometimes described as the "Anna Chennault Affair."[66] Thieu was promised a better deal under a Nixon administration.[67][66] Chennault agreed and periodically reported to John Mitchell that Thieu had no intention of attending a peace conference. On November 2, Chennault informed the South Vietnamese ambassador: "I have just heard from my boss in Albuquerque who says his boss [Nixon] is going to win. And you tell your boss [Thieu] to hold on a while longer." In 1997, Chennault admitted that "I was constantly in touch with Nixon and Mitchell."[68] The effort also involved Texas Senator John Tower and Kissinger, who traveled to Paris on behalf of the Nixon campaign. William Bundy stated that Kissinger obtained "no useful inside information" from his trip to Paris, and "almost any experienced Hanoi watcher might have come to the same conclusion". While Kissinger may have "hinted that his advice was based on contacts with the Paris delegation," this sort of "self-promotion....is at worst a minor and not uncommon practice, quite different from getting and reporting real secrets."[69]

Johnson learned of the Nixon-Chennault effort because the NSA was interfering in communications in Vietnam.[70] In response, Johnson ordered NSA surveillance of Chennault and wire-tapped the South Vietnamese embassy and members of the Nixon campaign.[71] He did not leak the information to the public because he did not want to "shock America" with the revelation,[72] nor reveal that the NSA was interfering in communications in Vietnam.[73] Johnson did make information available to Humphrey, but at this point Humphrey thought he was going to win the election, so he did not reveal the information to the public. Humphrey later regretted this as a mistake.[74] The South Vietnamese government withdrew from peace negotiations, and Nixon publicly offered to go to Saigon to help the negotiations.[75] A promising "peace bump" ended up in "shambles" for the Democratic Party.[73]

The election on November 5, 1968, proved to be extremely close, and it was not until the following morning that the television news networks were able to declare Nixon the winner. The key states proved to be California, Ohio, and Illinois, all of which Nixon won by three percentage points or less. Had Humphrey carried all three of these states, he would have won the election. Had he carried only two of them or just California alone, George Wallace would have succeeded in his aim of preventing an electoral college majority for any candidate, and the decision would have been given to the House of Representatives, at the time controlled by the Democratic Party. Nixon won the popular vote with a plurality of 512,000 votes, or a victory margin of about one percentage point. In the electoral college Nixon's victory was larger, as he carried 32 states with 301 electoral votes, compared to Humphrey's 13 states and 191 electoral votes and Wallace's five states and 46 electoral votes.

Out of all the states that Nixon had previously carried in 1960, Maine and Washington were the only two states that did not vote for him again; Nixon carried them during his re-election campaign in 1972. He also carried eight states that voted for John F. Kennedy in 1960; Illinois, New Jersey, Missouri, North Carolina, South Carolina, New Mexico, Nevada and Delaware. This was the last time until 1988 that the state of Washington voted Democratic and until 1992 that Connecticut, Maine, and Michigan voted Democratic in the general election. Nixon was also the last Republican candidate to win a presidential election without carrying Alabama, Arkansas, Louisiana, Mississippi, and Texas. This is the first time which the Republican Candidate captured White House without carrying Michigan, Minnesota, Maine and Pennsylvania.
He would be the last Republican Candidate to carry Minnesota four years later (in 1972), as of 2016. This is also the first time Minnesota voted for the candidate who did not eventually win since 1916.

Remarkably, Nixon won the election despite winning only two of the six states (Arizona and South Carolina) won by Republican Barry Goldwater four years earlier. He remains the only presidential candidate to win in spite of defending such a low number of his own party's states.[citation needed] All of the remaining four States carried by Goldwater were carried by Wallace in 1968. They would be won by Nixon in 1972.

Of the 3,130 counties/districts/independent cities making returns, Nixon won in 1,859 (59.39%) while Humphrey carried 693 (22.14%). Wallace was victorious in 578 counties (18.47%), all of which (with one exception of Pemiscot County, Missouri) were located in the South.

Nixon said that Humphrey left a gracious message congratulating him, noting, "I know exactly how he felt. I know how it feels to lose a close one."[76]

Nixon's victory is often considered a realigning election in American politics. From 1932 to 1964, the Democratic Party was undoubtedly the majority party, winning seven out of nine presidential elections, and their agenda influenced policies undertaken by the Republican Eisenhower administration. The 1968 election reversed the situation completely. From 1968 until 2004, Republicans won seven out of ten presidential elections, and its policies clearly affected those enacted by the Democratic Clinton administration via the Third Way.

The election was a seismic event in the long-term realignment in Democratic Party support, especially in the South.[77] Nationwide, the bitter splits over civil rights, the new left, the Vietnam War, and other "culture wars" were slow to heal. Democrats could no longer count on white Southern support for the presidency, as Republicans made major gains in suburban areas and areas filled with Northern migrants. The rural Democratic "courthouse cliques" in the South lost power. While Democrats controlled local and state politics in the South, Republicans usually won the presidential vote. In 1968, Humphrey won less than ten percent of the white Southern vote, with two-thirds of his vote in the region coming from blacks, who now were voting in full strength.[78]

From 1968 until 2004, only two Democrats were elected President, both native Southerners – Jimmy Carter of Georgia and Bill Clinton of Arkansas. Not until 2008 did a Northern Democrat, Barack Obama of Illinois, again win a presidential election.

Another important result of this election was that it led to several reforms in how the Democratic Party chose its presidential nominees. In 1969, the McGovern–Fraser Commission adopted a set of rules for the states to follow in selecting convention delegates. These rules reduced the influence of party leaders on the nominating process and provided greater representation for minorities, women, and youth. The reforms led most states to adopt laws requiring primary elections, instead of party leaders, to choose delegates.

After 1968, the only way to win the party's presidential nomination became through the primary process; Humphrey turned out to be the last nominee of either major party to win his party's nomination without having directly competed in the primaries.

This was also the last election in which any third party candidate won an entire state's electoral votes, with Wallace carrying five states.

This election was the last time until 1992 that the Democratic nominee won Connecticut, Maine, and Michigan and the last until 1988 when Washington voted Democrat. It was also the first time since 1888 that bellwetherCoös County, New Hampshire did not support the winning candidate,[79] which has occurred since only in 2004. This election was also the last time a Republican won the presidency without winning Alabama, Arkansas, Louisiana, Mississippi, and Texas.

Despite the narrow (0.7%) difference in the popular vote, Humphrey only took 35.5% of the electoral vote. This disparity prompted the introduction of the Bayh–Celler Constitutional amendment in Congress, which would have replaced the Electoral College with a direct election of the presidency. The effort was not successful and the Electoral College is still in force.

Converse et al. (1969) assesses the significance of the 1968 presidential election.[86] Many people were dissatisfied with Johnson but not with the Democratic Party. Their dissatisfaction was connected to the Vietnam War, civil rights, and law and order. Humphrey, the choice of an older generation, suffered from identification with the Johnson administration. Wallace attracted many Richard Nixon-bound Democrats and thus was a threat to Nixon. McCarthy's popularity in the New Hampshire primary was a nondifferentiated anti-Johnson vote from which many voters went to Wallace. These were not, however, the hard-core McCarthyite followers. Wallace's success was the result of the voter's identification with his stand on the primary issues – continuing segregation, getting out of Vietnam, a focus on liberal[clarification needed] economic policies and law and order. Wallace's supporters were rural and small town residents in the South and skilled labor in the North. They were disgusted with public policy and were often alienated from politics.[87]

"The activities of the Nixon team went far beyond the bounds of justifiable political combat. It constituted direct interference in the activities of the executive branch and the responsibilities of the Chief Executive, the only people with authority to negotiate on behalf of the nation. The activities of the Nixon campaign constituted a gross, even potentially illegal, interference in the security affairs of the nation by private individuals."

^ abAlthough he was born in California and he served as a U.S. Senator from California, in 1968 Richard Nixon's official state of residence was New York, because he moved there to practice law after his defeat in the 1962 California gubernatorial election. During his first term as president, Nixon re-established his residency in California. Consequently, most reliable reference books list Nixon's home state as New York in the 1968 election and his home state as California in the 1972 (and 1960) election.
